Abstract

This paper describes a method of developing a Defect Oriented Test (DOT) strategy by using Inductive Fault Analysis (IFA) and layout dependent fault models extracted from process defect statistics. The results of a quantitative prediction of the effectiveness of several test strategies, such as functional, IDDQ, and a low voltage power supply method, on a current-mode Digital to Analogue Converter are discussed and show that no single test method is superior.
